This study aimed to compare the diagnostic efficacy of BRAF^(V600E) mutation and the Thyroid Imaging Reporting and Data System(TIRADS) classification in differentiating papillary thyroid cancers(PTCs) from benign lesions among BSRTC I, III, and V nodules.Methods: A total of 472 patients with 479 nodules were enrolled in this prospective study. Ultrasound, BRAF^(V600E) mutation testing, and FNAC were performed in each nodule, followed by surgery or regular ultrasound examination.Results: In the BSRTC I category, BRAF^(V600E) showed similar sensitivity, higher specificity, and lower accuracy when compared with TIRADS. In the BSRTC III/V category, the sensitivity, specificity, and accuracy of BRAF^(V600E) were similar to those of TIRADS. In comparison to BRAF^(V600E) alone, the combination of the two methods significantly improved sensitivity(BSRTC Ⅰ:93.6% vs. 67.7%, P < 0.01; BSRTC Ⅲ: 93.8% vs. 75.0%, P < 0.01; BSRTC V: 96.0% vs. 85.3%, P < 0.001). When compared with TIRADS alone, the combination improved sensitivity in BSRTC Ⅰ nodules(93.6% vs. 74.2%, P < 0.05), increased sensitivity and decreased accuracy in BSRTC III nodules(93.8% vs. 75.0%, P < 0.01, 91.0% vs. 93.6%, P < 0.01), and improved both sensitivity and accuracy in BSRTC V nodules(96.0% vs. 82.0%, P < 0.001; 94.2% vs. 81.3%, P < 0.001).Conclusions: BRAF^(V600E) exhibited higher specificity and lower accuracy compared with TIRADS in BSRTC Ⅰ nodules, while the two methods showed similar diagnostic value in BSRTC Ⅲ/Ⅴ nodules. The combination of the two methods distinctly improved sensitivity in the diagnosis of PTCs in BSRTC Ⅰ, Ⅲ, and Ⅴ nodules.展开更多

Methods: The electronic synoptic report was developed using a relational database based on elements from TIRADS and a multidisciplinary consensus statement for thyroid reporting. A retrospective analysis of 138 patients with previously reported thyroid sonographic exams was evaluated for the presence of these elements. The electronic synoptic report calculates the TIRADS score and generates a formal report. Using the TIRADS score the potential decrease in unnecessary FNAB was estimated. Results: Key TIRADS elements were variously reported ranging from 43% for the thyroid nodule’s architecture as solid or cystic. Thyroid nodule echogenicity and calcification was commented in 27% and 23%, respectively. Other features of the TIRADS score were commented in 0% to 8% of the official reports. Estimated reduction for potentially reduced need for FNAB was 34.5%. Conclusions: This study is the first implementation of synoptic reporting using a relational database for sonography of thyroid nodules. Implementation of an electronic standardized synoptic reporting system may facilitate more accurate, and more comprehensive reporting for thyroid ultrasound scanning of thyroid nodules. The use of TIRADS was estimated to be able to potentially reduce the need for FNAB which was significant.展开更多
